According to Chinese legend, after harnessing rivers on the Chinese land, Da Yu divided the land mass into nine regions with Yangzhou covering present-day Jiangsu, Zhejiang, Jiangxi and Fujian. It was a land of legends. The Dynasty of Zhou established the state of Han in Yangzhou. In late Spring and Autumn, Pu Cha, the King of the State of Wu, spearheaded his army northward in a hegemonic move. He conquered the State of Han and dug a canal and built a city. The city of Yangzhou gradually took shape. When the state of Chu defeated the State of Yue, it remodeled the city and renamed it Guanglin. It was called Yangzhou during the ninth year of the reign of Emperor Kai of the Sui Dynasty. As an administrative area, Yangzhou was historically called Hancheng, Guanglin, Jiangdu, Hanjiang, Ganquan, Weiyang with unique features of each.
